Upon the frame-Werl: S ellen mounted e eawy ring oi sniinble i einwenig; me* 13 insieme?. fio the ire-inenirorii of `screw l-l. The ring Ilfzl is provided Willi wllioli may' 'be snapped. on io lle face of the eonlroller ns shown in 2. The Cover 2li is preferably provided with n Central emily or dome 27 'provided with n spring inioroed anp 28 adapted to benr'agninst the end oi' the innin bearing' 5 as shown. 29 nlml 2X0 are concentric rings similar vto 'the rings 1l und l?, und nre also provided with the 2l and nre spring clamping.-

ball bearings 31. Between these ball bear- "i' ings spiral springs may alsoA oe provided ns shown nt 32 in Fig. l provldlng what is generally known as the annuler rim type of lvnll bearing. The projection 33 of the onlin ber ing 5 is elongated in cross section thereby providing n key io enga e the benringl fl upon Awinch is monntec the inner ring 30 of the ball bearing which is free io turn independently of the outer ring 29. By this nrrnngemeinI it will loe observed that when the easing 8 is adjusted oy i1he'exiension 9 and fixed in n permanent position the innin bearing 5 moy be set in rotation by ihe shaft of the engine and revolve freely n'pon elle ball bearings i2. `Wlile this is going on .it Will also be observedthnt the elongated projection 33 oi the main bearing carries with it in iis rotation die bearing 3 provided with thevelongaed opening 35A and provided with the spiral spring 36' adapted o constantly force 'the bearing 34: ontl of center and. ns a naturel consequence throw oni` of center the rings 29 and 30 pro-v vided with the bell bearings 31. In his Way P011 Every revolution of the main-" bearing 5 lie outer ring' 29 or rolling eonjl meting device of elle nell bearing rolls in successive Contact with eaelo of the seg mente l5, 16, 17 and 18 and is rso propori-ioned that the Contact with each segment is broken before Contact with the preceding ysegment is instituted, so that it will be seen tbe inner ring 30, ball bearings 3l and outer ring 29, through eecli segment es passed und from there into its binding post, through the sparking apparet-us rand back to' the ground,

Various modifications may be made without dein/uiting from the spirit ot the invention.

Having described the invention7 what claim as new7 Aand desire to secure by Letters Pnt-ent, is: i

1. In? a circuit controller, a casing member and an axial member, each of said members being' adapted to be connected to :in electric circuit, e rolling contacting device noemer@ vVice comprising eccentrically mounted concentric rings.

EZ. ln a circuit controller, e casing me1nbei' and an axial member, each of said mem bers being adapted to be connected to an electric circuit, a, rolling contacting device eccentrically mounted upon one of said members, said contacting device being adapted toelectrically connect said mem-- bers during each revolution of one of seid members, said rolling contacting device comprising eccentrically mounted concentric rings, and bells separated by springs between sad rings.

In testimony whereof I affix my signature in prese-nce of two witnesses.
